Description
Summary:The working principle of ground automatic neutral section passing system of electronic switch was introduced. The calculation of electrical parameters of catenary, traction load and phase passing device and system simulation modeling were carried out. The equivalent model of the locomotive passing through the phase separation zone on load was established based on the ground automatic passing of the electronic switch. The key parameters of RC branch were designed by considering suppressing reactive voltage and maintain SCR in on-state. Finally, the effectiveness of suppressing overvoltage was validated by simulation.
